Special Series Frequency Converter 125A and 160A for Efficient Power Control

The frequency converter converts the input three-phase linear voltage 380V, 50Hz, into an output three-phase voltage of 230V, 400Hz. The load is continuously fed from inverter output through a fused switch. The rectifier receives the electrical energy from the mains and supplies the load power from the mains and supplies the inverter with DC power.
